WHITE-WINGED SCOTER.

165. Oidemia deglandi. 22 inches.

This is the largest of the Scoters, and may easily be distinguished from the others by the white speculum on the wing and a white comet extending from the eye backwards. It also has a yellow eye.

This species often feeds in very deep water, like others of the family.

Nest.—They nest on the ground, generally in long grass or under low bushes, making a coarse nest of grasses, and sometimes twigs, lined with feathers; 6 to 8 pale buff eggs (2.75 × 1.70).

Range.—North America, breeding in British Columbia and Alaska.
